isanders, and has a special reference to those parts of a track sander in and adjacent to the sand dome of a locomotive.

Ono ob ect of the invention is to provide an im roved eneral mechanism for such a device.

Another object of the invention is to provids on im roved form of sand dome base and airout et therefrom. With these, and other ob ects in view as will hereinafter become apparent, the inven tion consists of certain novel details of er.-

rangement, and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically set forth in the claims.

In the accompanying drawings, like charactors of reference indicate like parts in the several views, and; Figure .1 is a view of the improved sander taken centrally through the improved arrangement of the air inlet and sand outlet pipc. Fig. 2 is a plan viewot a sand dome constructed in accordance with this invention, the top and casing being removed. Figli; is a detail of the connection between the gravity and force pipes in such a dome. Fig. 4 is a view of a modification showing a novel method of introducing the air blast and the connections therewith.

. Fig. 5 is a side elevation of a modification of Fig. 4. Fig. 6 is a sectional view on the line AA of Fig. 5.- Fig. 7 is a sectional view of another modification ol' the denies. Fig. 56 is a modified form of the nozzle shown in Fig. 1. Fig. 9 is a modified form of the air nozzle shown in Fig. 1. Referring now to Figs. 1, 2 and 3. in the views here shown there is indicated a sand dome provided with a iressure or air blast feed, and a gravity fee for the sand.

'lho numeral 10 indicates a sand dome base which arranged to lit the hoileriu the usual nmnnor. ./\l'. 11 is shown bottom which in this iuvl-uliou is coni al in l'o'rni'with the upon 01' the cone dounwurd.

Iii-the preferred manner of constructing the th sand donu 1 device, there is provided a pair of laterally l disposed outlet pipes 12. It is obvious however, that these pipes may be formed separately from the dome base and may be screwed on or otherwise attached thereto; The inner ends of these pipes, as shown at 13 are spaced apart. A compressed air pipe 14 extends inrrard to a point near the longitudinal cen tral plane of the device and is there bent downward as shown at 15. The lower end of this pipe is provided with a tee connection having branches 16 provided with flaring or I straight ends as clearly shown in Fig. 1. It is to be noted that the ends 13 of the ripe 12 are so arranged as to mer e gradua yvinto the bottom 11 of the sand dome, and that the ends 16 of the air inlet are arranged in such manner as to force the sand contained in the apex or near the apex of the sand dome bottom through the pipes 12, the axis of the inlet being disposed at or below the axis of the outlet pipes The outlet pipes 12 are provided on their outer ends with threaded portions 17 to each of which is attached a nipple 18. The admission of air, under pres" sure, through the )ipe 15 is controlled by a suitable valve in the "cab of the engine, not deemed necessary here to be shown.

In the lorm ol the device indicated in F 1 to 3 inclusive. the gravity su ply is through pipes 19 opening upward tirough bosses 20 formed in the bottom of the dome base in such manner that their upper surfaces are substantially horizontal. A gate 21, actuated in any suitable manner from the engineers cab is held to close the mouths of the passages or pipes '19. The outer ends of nor to the ends 17 of the pipes 12. Attached to the outer ends of the pipes 19. are nipples 32, a Y 23 conncrts the nip )les 32 and 18011 each side of the dome, $111k the Y is so arranged that the passage from the nip le 18 is direct, while that from the nipp e 32 forms the branch of the Y. A i o neets to the stem of the Y, am leads from that point down to a suitable point near the rail for the deposition of sand thereon inadvance of the driving wheel otthe locomotive.

there is a dire t supply of sand froin the pressure p pc.

It will he observed that the device us here shown coin u'isos both gravity and air feed for the sum [1. is obvious that the air fo d 110 the pipes 19 are screw threaded in like man- 24, con-- 1110 it is to be noted that with this arrangement Q ssasso may be used alone, in which case the feed pipes will be located centrally of the longitudinal section of the dome. In either case it is to be noted that the sand supply is by direct air blast, and not as is usual by indirect suction and air blast. 1

In Fig. is shown one modification of the device, the same being in the form of a dctachable sand pipe casting 25 rovidcd with an' air' passage .26 extending ongitudinally therethrough. Each end of the air passage is recessed and threaded asindicated at 27 and the inner end is provided with a raversely bent air nozzle 28 having a daring or straight month as at 29. The outer end or" the air passage has an air pipe 30 screwed therein which receives air from the usual source. Figs. 5 and 6 show arnodification of this formof the invention wherein the air is introduced from the side and the air passage 26 is in they form of a tee. In this case it is preferred to' employ a plug 81 for the pur: pose of closing one end of the tee portion of the air assage. It is obvious that with either of these forms a straight or flaring nozzle may be used as desired. p

In Fig. 7 is-shown a form of the device especially adapted for application to existing ,1 sand do es where the sand pipes extend jace'nt to said sand pi e.

able nozzle 25 is brought in preferab downwar as indicated in that figure. In this form of the invention the usual detachrovided and-the air is y as indicated Fig. 4, although the air may be let in as shown in the dotted lines in Fig. -7. In place of the ordinal rebentnozzle 28 there is here shown a modi cation thereof as indicated at 32, the principles of which are however, identical.

, It is-to be noted that in all of-the devices shown inFigs. 4 to 7 theair nozzle is up' provided a simple and which is entirely free from many of the objectionable features existing in other devices of-Like character. s
